FOLDER AND PRESSER FOR ENVELOPE-MACHINES.

SPECIFICATION forming part of Letters Patent No. 453,389, dated June 2, 1891. Application filed May 23, 18%. Serial No. 352,864. (No model.)

To (all whom it may con/(07%:

' Be it known that I, AER-AM A; RHEUTAN, of

ence being had to the accompanying drawings, forming a part of this specification, and

in which- I v Figure 1 represents a planof myimproved folder and presser, also the folding-bed with an envelope thereon and a part of the main bed of an envelope-machine. Fig. 2 represents a similar view of part of said envelope and beds and my device turned up vertically to show a front view thereof, with the presser removed to illustrate the other parts coming back of the same more fully. Fig. 3 is a cen tral longitudinal section on line A B, Fig. 1. Fig. 4 is a detached plan view of the presser upon an enlarged scale, the two following figures also being upon the same enlarged scale. Fig. 5 is a detached plan of the folder; and Fig. 6 is a transverse vertical section on line C D, Fig. l.

My invention relates to improvements upon the folder and presser covered by my United States Patent No. 335,244, dated February 2, 1886, the object thereof being to simplify the construction, so that the device may not only be made more cheaply, but also operated in a more satisfactory manner to effect the desired resnltviz., to fold the back flap and to press upon the said back flap and the side flaps to unite the overlying 'gummed edges thereof, the same having been previously gummed and the side flaps folded in the usual way.

In order that others may better understand the nature and purpose of my said improvements, I will now proceed to describe the same more in detail.

In the drawings, E represents the carrier or frame which supports the presser F, and is provided with journals E E at the ends, fitted to turn in bearings G G, secured to the main bed H, and to one of said journals, outside of its bearing, is secured a crank I,

suitable connection with the main shaft or other source of 'powerin the machine. Alongitudinal shaftJ is centrally securedimthecarrier-journals E E, and the folder K is fitted to turn thereon between said journ als E.

The presser F is pivotally attached to the upper forward part of the carrierin a similar manner to the one in my patented device, being so hungon a pivot a, passed through a lug b on the carrier, as to freely vibrate or swing in and out with a slightmovement on said carrier,sufticient space (see Fig. 6) being allowed between the under side of the lug b and the presser to permit of said swinging movement. It therefore adapts itself automatically to any variation in the thickness of either the paper or the fold and at the same time produces a firm and positive pressure over the whole surface of the edges to be united, the same as in my old device.

A constant downward yielding pressure is imparted to the folderK by means of suitable springs preferably interposed between the carrier and top of said folder. In this instance spiral springs c c are shown for said purpose, the same being fitted over upright pins d d, secured in the folder, which pass up through suitable vertical openings 6 e in the carrier or frame E. Said springs are held in position vertically between the top of the folder and suitable shoulders d d on the carrier. The pins are rigidly secured in the folder, and therefore serve not only to hold the springs 0, but also to control the downward movements of the folder by their upper ends striking against the carrier at the ends of. slots or openings 6 when the folder is swung down into the position shownin Fig. 6.

The various parts of the device are constructed and arranged to bring the center of shaft J and the bottom of the folder (when the latter is in its lowest or normal position) a little above the level of the top of the folding-bed L, or aboutthe height of two thicknesses of envelope-paper, as is shown in Fig. 6. By this construction the folder is always secure against injury in swinging the device over onto the folding-bed, as in the operation of folding and pressing an envelope.

The shaft and folder may be elevated and which may be connected by means of any lowered to operate upon different thicknesses of envelopes or to vary the thickness of fold by adjusting the bearings G G, which support the same. This is done by turning the holding-screws ff and set-screws g g, as required, to effect said adjustment in a similar manner to that described in my former patent previously cited.

It will be apparent from the foregoing description and reference to said former patent that I have greatly simplified the construction as well as the operation of the folder and presser device, said construction in my present device being such as to admit of both the folder and presser being operated together by one crank instead of independently by two separate cranks, as in my old device,while at the same the result produced is more satisfactory, as, both the folder and presser bein g operated simultaneously, as aforesaid, the trouble and expense incident to constructing and timing two separate operating mechanisms so as to work properly and in unison is entirely obviated.

Having now described my invention, what I claim therein as new, and desire to secure by Letters Patent, is-- 1. In an envelope-machine,a folder mounted and fitted to turn on a rocking carrier, and said carrier, in combination with means whereby said folder may be permitted to yield upward as well .as controlled in its downward movements, consisting of rigid pins secured in the folder and extending up through suitable openings in the carrier, and suitable springs interposed between the folder and carrier, substantially as set forth.

2. In an envelope-machine, a folder fitted to turn on a shaft secured in a rocking carrier, in combination with said shaft and carrier, suitable hearings in which the carrier may in turn rock, and means connecting the folder and carrier, consisting of rigid pins secured in the folder-and extending up through suitable openings in said carrier, and suitable springs interposed between the folder and carrier, whereby said folder is permitted to yield upward as well as controlled in its downward movements, substantially as set forth.

3. In an envelope-machine, a folder fitted to turn on a shaft secured in a rocking carrier and held down by a yielding pressure from said carrier, in combination with the carrier, substantially as set forth.

at. In an envelope-machine, a folder mounted and fitted to turn on a shaft secured in a rocking carrier, in combination with said shaft and carrier, suitable bearings for sup porting the carrier,'a suitable spring interposed between the folder and carrier, rigid pins extending up from the folder through suitable openings in the carrier, and a presser pivotally attached to the carrier. substantially as set forth.

5. In an envelope-machine, the combination of the folder K, having the upwardly-projecting pins d d thereon,\vith the shaft J and carrier E, substantially as set forth.

6. In an envelope-machine, the combination of the rocking folder K, having the upwardly-projecting pins d (l thereon, with the carrier E and Springs 0 c, substantially as set forth.

'7. In an envelope-machine, the combination of a rocking spring-folder K with the shaft J, secured in the carrier-journals E E, carrier E, and vertically-adjustable bearings G G, substantially as set forth.
